| Abstract: | The phase diagram of the one-dimensional extended Hubbard model with halffilled-band has been obtained by using the bosonization method. It shows that there exist four different phase regions with the varying of the interactions. The properties of the model in various phase regions are studied in detail and the results are compared with others. |
